Convert the stock dovetail to a standard Picatinny scope mount with *25MOA built into the rail. Adds the extra elevation(MOA) for 22 long rifle so you can set your scope "zero" at 200yrds and beyond for those long shots.

Great for Weaver and Picatinny rings or quick release rings so you can easily swap optics between rifles. 4 supplied set screws hold the mount firmly to the receivers dovetail. No drilling or tapping required for installation.
